The Mangaroon orogeny was an orogenic event in what is now Western Australia between 1.68 and 1.62 billion years ago in the Proterozoic, preserved in the rocks of the large Gascoyne Province.
Beginning 1.7 billion years ago, widespread sedimentary rocks deposited across the Gascoyne Province, including fluvial conglomerate and sandstone.
During the Mangaroon orogeny, huge volumes of granite belonging to the Durlacher Supersuite intruded rocks in the Mangaroon Zone as high-grade metamorphism and deformation occurred.
Like the Capricorn orogeny, the Mangaroon orogeny is interpreted as an intracontinental deformation event due to distant collisions at the edges of the continent rather than an ocean-closing event.
